Not bad!

For a first song, that is not bad at all! I really enjoyed the intro (up to 7 seconds). It gave the beginning a feel of suspense. You used good synths, better synths than I used when I started. I liked the melodies. I also like how you made the main synth glide from not to note.
If I could improve some things about the song, I would first give it a stronger kick / bass drum beat. That would help it feel more driving and techno-ish. Personally, I would do the bass notes on the offbeats instead of having the bass start on the first downbeat and hold through the whole bar.
Other than that, I liked your creativity. Keep working - you are already better than lots of people at FL, or even music in general.
